CHIMNEY-CAP.

SPECIFICATION forming part of Letters Patent No. 361,871, dated April 26, 1887. Application filed February 14, 1857. Serial No. 227.610. (No model.)

Be it known that I, HIRAM F. HENRY, of

v Gowanda, in the county of Oattaraugus and State of New York, have invented a new and useful Improvement in Chimney Gaps, of which the following is a specification.

The object of my invention is to provide an improved chimney-cap which offers the least possible resistance to the smoke and products of combustion,and at the same time effectually prevents the entrance of wind to impede the upward tendency of the same; and to this end my invention consists in the peculiar construction and arrangement of parts, as hereinafter fully described, and pointed out in the claims.

Figure 1 is a perspective view of my improvement. Fig. 2 is a sectional elevation of the same, and Fig. 3 is a perspective view showing the same provided with a saddle or deflector in the fork of the branches.

Similar letters of reference indicate similar parts in all the figures.

Referring to the drawings, A represents the cap, which is composed of a section of pipe, a, provided with the'upwardly and outwardly projecting sections or branches 1), the whole forming a Y-shaped cap. The sections or branches 1) are of the same size as the section a, and project but a short distance beyond the section a. The angle a formed by the sections or branches 1), is directly over the center of the section a, so that the products of combustion will be divided and deflected outward in their passage through the cap. In front of the said sections, and a short distance from the ends thereof, I secure shields or plates 0, of the size and shape of the openings therein, by means of the bars or braces d, and to the said plates d, I secure the cones e.

WVhile I do not restrict myself to the distance the sections or branches 7) project beyond the section a, or the distance the plates 0 are to be from the end of the said sections, yet I prefer the branches to project about an inch on their under sides from the pipe a and the plates to be about the same distance from the end of the branches. If desired, a saddle or deflector, f, may be placed in the fork of the branches and at right angles thereto, as shown in Fig. 3.

A cap constructed as above offers little or no resistance to the escaping smoke and products of combustion, as they will be divided by the angle a and deflected without retarding their progress, and the branches each being of the same size as the pipe-scction a, the capacity for delivering is doubled. The cones at the ends of the branches prevent the wind from blowing into the cap, and they, with the saddle, deflect the wind so as to cause it to pass over the space between the cones and the ends of the branches, thereby increasing the draft. 7

I am aware that caps have been provided with inverted cone shaped deflectors supported above the top of the pipe. I am also aware that shields in front of openings in a cap are old; and I am further aware thatacylindrical band mounted on a pipe has been provided with flaring or funnel-shaped flanges, and I therefore do not claim such inventions.

Having thus described my invention, what I claim as new is 1. A chimney-cap consisting ofa section of pipe provided With outwardly and upwardly projecting branches having their angle of meeting directly over the center of the said pipe, and provided with im'peri'orate deflecting-cones secured a short distance from their ends, substantially as herein shown and described.

2. A chimney-cap consisting of a pipe provided with upwardly and outwardly projecting branches at its upper end, having their angle of meeting over the center of the pipe,

plates secured a short distance from the ends of the said branches, imperforate cones on the said plates, and a deflector in the angle of the branches, substantially as herein shown and described. I
